All the point: just narrated by the Doctor were contained in it.

I now state to your highness that I will keep it all as becomes a prince, and conform to it." Thereupon he gave the Elector his hand .-- What now was the amount and meaning of this promise on the part of the Prince?
Almost nothing.

He would conform to the demands of the Elector, exactly as he had hitherto said he would conform to them.

Taken in connexion with his steady objections to sign and seal any instrument on the subject--with his distinct refusal to the Landgrave (through Knuttel) to allow the Princess an evangelical preacher or to receive the sacraments in the Netherlands--with the vehement, formal, and public protest, on the part of the Landgrave, against the marriage--with the Prince's declarations to the Elector at Dresden, which were satisfactory on all points save the religious point,--what meaning could this verbal promise have, save that the Prince would do exactly as much with regard to the religious question as he had always promised, and no more?
This was precisely what did happen.

There was no pretence on the part of the Elector, afterwards, that any other arrangement had been contemplated.
The Princess lived catholically from the moment of her marriage, exactly as Orange had stated to the Duchess Margaret, and as the Elector knew would be the case.
